Executive Summary

Boat owners—about 5 million active users—routinely face small parts failures and need fast, precise replacement parts and on-water repairs, but current niche e-commerce listings are fragmented, have long lead times, and lack reliable fitment information, which depresses conversions and increases costly downtime. This pain affects both DIY owners and service shops that must charge premiums or delay work when parts aren’t available or don’t fit. You could build a vertically focused platform that combines a shoppable short-form content layer (TikTok/Instagram integrations), an automated fitment wizard, on-demand 3D-printed custom parts for hard-to-find items, and a marketplace for same-day local repair technicians and marina partners. The product would prioritize real-time local availability, simplified purchase-to-schedule flows, and fulfillment options (local pickup, same-day 3D print, or expedited shipping) to minimize time-to-fix. The market is compelling: roughly $2.5B in annual spend (5M owners × ~$500/year) and rising interest in social commerce and willingness to pay premiums for fast, reliable on-water service mean there’s room for margin and growth. If you can crack the operational challenges—lowering customer acquisition cost through social funnels, reliably onboarding local technicians, and scaling custom-part fulfillment—this focused offering can outcompete general marketplaces by delivering higher conversion, faster time-to-fix, and fitment guarantees, though logistics and capital for local rollout will be the primary hurdles to manage.
